301.02.0057 Compatible Air Dryer Valve — DAF & Iveco

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system of heavy commercial vehicles by managing air quality. It works to remove moisture, oil, and particulates from the compressed air stream, preventing corrosion and freezing within the brake lines. Built with high-strength components, it maintains consistent pressure regulation for optimal braking performance.

Vehicle compatibility and fitment

This component is specifically designed for use in DAF and Iveco trucks. It is also compatible with WABCO systems, ensuring seamless integration into existing pneumatic architectures. This part serves as a reliable replacement for maintaining system integrity in heavy-duty applications.

Installation and maintenance guidance

For proper installation, technicians should verify the 24V electrical connection and ensure all port connections—including the M22x1.5 and M12x1.5 interfaces—are tightened to specification. Regular inspections of the purge cycle are recommended to prevent moisture buildup in the lines.

System reliability

Maintaining a clean air supply is essential for the longevity of all pneumatic components. Using high-quality valves helps prevent premature wear in the braking system of heavy vehicles. Consult your authorized distributor.
